x11/pixman: update to 0.36.0

[vishwin]

Summary

See also PR 233737

https://lists.freedesktop.org/archives/pixman/2018-November/004793.html

While here, update WWW.

On armv6 and armv7, fix build by disabling extensions that aren't supported, as autodetection is dodgy.

Test Plan

Passes testport on 12.0-RC3 armv7 and 13-CURRENT amd64 and aarch64 at least. Probably needs exp-run.

x11/pixman/Makefile

31

armv7 target on FreeBSD always provides NEON, so this would be pessimization.

$ cc -dM -E -</dev/null | fgrep -i neon
#define __ARM_NEON 1
#define __ARM_NEON_FP 0x4
#define __ARM_NEON__ 1

[jbeich]

Adding Mikaël to review arm* bits. Not enough details why --disable-arm-* is required i.e., builds fine here.

• 11.2 armv6
• 13.0 armv7

[vishwin]

The ARM SIMD and NEON assembler bits fail to link when LLD is the linker, even with 0.34.0. No mitigations (not even CFLAGS+=-fPIC) save for possibly forcing BFD use work. Last successful armv7 build on my machine was 120083.

Leaving those two aforementioned bits enabled (regardless of CFLAGS+=-fPIC) result in the same error messages for this new version.

If armv7 bustage isn't a regression from 0.36.0 update then it should be in a separate bug/review.

No mitigations (not even CFLAGS+=-fPIC) save for possibly forcing BFD use work.

Have you tried -Wl,-z,notext (a la rP484698)?

Considering.

Second item tried after CFLAGS+=-fPIC; replace the above error output's can't create dynamic relocation R_ARM_V4BX with unrecognised reloc 40; same addresses as well.

It may be because there are multiple cflags in the makefile, for ex: GTK_CFLAGS SSE2_CFLAGS etc.

[vishwin]

Remove workaround for LLD on armv6/armv7, split to separate issue

[vishwin]

Rebase after rP486510 and rP486511
